Boat is new to me and has wrong prop on it . Mercury 150 2.5 1995 has a high five 21p on it and will go over 6k . At 6 k 56 mph gps . No jack plate but runs good, good hole shot and accel. I don’t need max speed just a good performer and staying inside of rpm limit. Always run light on tackle and gas. Boat needs some lift up front.
